Penn State and Westinghouse make eVinci microreactor plan official
Penn State and Westinghouse Electric Company are working together to site a new research reactor on Penn State’s University Park, Pa., campus: Westinghouse’s eVinci, a HALEU TRISO-fueled sodium heat-pipe reactor. Penn State has announced that it submitted a letter of intent to host and operate an eVinci reactor to the Nuclear Regulatory Commission on February 28 and plans to engage with the NRC on specific siting decisions. Penn State already boasts the Breazeale reactor, which began operating in 1955 as the first licensed research reactor at a university in the United States. At 70, the Breazeale reactor is still in operation.

Design, procurement, fabrication, and performance testing of control rod materials for the EBWR are reviewed. Construction of the EBWR afforded an opportunity to reduce control rod costs by using a newly developed stainless steel alloy containing high concentrations of natural boron. Costs and performance (to date) of these rods are compared with hafnium-Zircaloy 2 rods.
